Vanda plant named ‘SPCDW1310’

ABSTRACT

A new and distinct  Vanda  cultivar named ‘SPCDW1310’ is disclosed, characterized by unique flower coloration of violet with small specks of white and large flower size. The new variety is a  Vanda , typically produced as an indoor ornamental plant.

Latin name of the genus and species: Vanda hybrid.

Variety denomination: ‘SPCDW1310’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda hybrid. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘K42RB’ with the unpatented, proprietary pollen parent referred to as Vanda ‘JB4N’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in December of 2000.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in February of 2006 in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1310’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SPCDW1310’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in June of 2007. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1310’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1310.’ These characteristics in combination distinguish ‘SPCDW1310’ as a new and distinct Vanda cultivar:

-   -   1. Unique flower coloration of violet with small specks of         white.     -   2. Large flowers.

PARENT COMPARISON

Although the inventor has records of the name of the seed parent, Vanda ‘K42RB’ he no longer has record of the phenotypic characteristics of the seed parent. Comparison cannot be made.

Although the inventor has records of the name of the pollen parent, Vanda ‘JB4N’ he no longer has record of the phenotypic characteristics of the seed parent. Comparison cannot be made.

COMMERCIAL COMPARISON

‘SPCDW1310’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘SPCDDW1109’ in most horticultural characteristics. However the new variety, ‘SPCDW1310’ differs from ‘SPCDDW1109’ in the following characteristics:

-   -   1. The new variety has violet flowers with small white specks.         The comparator variety has a light yellow background coloration         with dark purple spots and a violet margin.     -   2. Different lateral sepal shape.     -   3. Narrower lips.

‘SPCDW1310’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘Exotic Purple’ in most horticultural characteristics. However the new variety, ‘SPCDW1310’ differs from ‘Exotic Purple’ in the following characteristics:

-   -   1. Darker flower color.     -   2. Sepals and petals have less white coloration.     -   3. Leaves are more upright.     -   4. Different lip shape.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW1310’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. The plant is 5½ to 6½ years old. Described plant is in a hanging basket without soil. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SPCDW1310’ plants grown in a commercial greenhouse in Honselersdijk, the Netherlands. The plant is 5½ to 6½ years old. Described plant not container-grown, but in a hanging basket without soil. Temperatures ranged between 19° C. and 23° C. day and night. No photoperiodic or chemical treatments were given to the plants. During bright Summer conditions, shade was given. During dark Winter months, no supplemental light was given. Measurements and numerical values represent averages of typical plant types.

After deflasking they     remain in shade under local outdoor temperatures. -   Root description: Moderately to heavy rooting with aerial roots     only. Roots very fleshy, non-fibrous. Average length of old roots:     34.3 cm, average diameter of old roots: 0.3 mm, average diameter of     young roots: 0.6 cm. Old roots colored yellow-green; near RHS 146D.
